After a close run first practice between they and the lone Toyota the two Audi stamped their authority on the Six Hours of Silverstone in the second session, both cars lapping over a second quicker than their nearest rivals.

In another change, after Benoit Treluyer and the hybrid e-tron quattro topped the first 90 minute session it was Tom Kristensen in the diesel-only R18 ultra that set the best time in the later session. The Dane set the time, at 1:45.645 a shade faster than Treluyer’s P1 time 37 minutes into the session.

In fact both he and co-driver Allan McNish set faster times than the reigning Le Mans champions in the #1 hybrid Audi.

Marcel Fassler was the best of the trio in the R18 e-tron quattro, but perhaps the best performance of the session was that of Danny Watts and Strakka Racing. Watts’ 1:46.994 was good enough to break up the manufacturer domination at the head of the time, pushing the Toyota TS030 Hybrid to only fourth fastest. Alex Wurz’s time was nearly 1.5 seconds slower than Kristensen’s benchmark, though the Toyota squad’s practice time was limited to just 24 laps (compared to the 43 and 40 of the two Audis and Strakka’s 37) by an electrical problem.

Just as in the opening session the top seven in LMP2 squeezed into juts under a second. After lying just over the second barrier in the times in the opening session it was the Jota Zytek that was fastest in the class thanks to Nicolas Minassian, the Frenchman joining regular drivers Sam Hancock and Simon Dolan at the British team for the weekend.

With the closely packed standings in mind it is a mark of Jota’s and Minassian’s pace that the next best car and driver combination (OAK Racing and Dominik Kraihamer) were more than four tenths slower.

Ferrari squads were once more dominant in the twin GTE classes. Marco Cioci – who shares the GTE Am AF-Waltrip 458 Italia with Matt Griffin and Piergiuseppe Perazzini – repeated his feat of the first practice to once more set the best class but after co-driver Gianmaria Bruni led GTE Pro in the first session Giancarlo Fisichella took the honour in GTE Pro, with Team FelbermayrProton Porsche man Richard Lietz less than a tenth slower.

Meanwhile Jonny Adam – the former BTCC driver, turned British GT race winner – was second fastest in GTE Am, though the Scot on his World Endurance Championship bow with Aston Martin Racing was more than a second slower compared to Cioci.
